The government's been accused of exaggerating the numbers of houses built to protect itself.
It's after new census figures showed that the number of new homes built in the last few years falls far short of what was promised.
The census figures released earlier show that only 2% of all houses and apartments occupied nationwide at the moment are new, built between 2011 and last year. 11,572 new homes were built in Dublin during that time.
But the government's figures are more than twice the CSO's. DIT Housing lecturer Lorcan Sirr says the problem is the way the government counts new homes. "The way the Department of Housing count a new house is by connection to the ESB grid, which is all well and good when it's a new house that's just been built," he said. "But over the last few years, we've seen houses partially built and now finished, or completed but left empty. When a house is empty for two years or more it has to be re-connected to the ESB grid for safety reasons. That then gets counted as a new house for the second time"
Housing Minister Simon Coveney is now under fire over the apparent gap between the number of new homes we should have by now and what we've actually been left with. Lorcan Sirr says the reason we're seeing such a difference is probably political. "They've been deliberately using a method they know is wrong, probably to protect the Minister," he said, "because when the real numbers come out they don't look very good for the Minister, or the Department, because they can't count houses!"
